The strategy of circulation in Tunis aims to :

• To grant the priority the pedestrians.
• To control the traffic in the center town .
• Improvement of the traffic by the adoption of the discharged traffic.
• The encouragement with the use of public transport in the center town and improvement, even in a relative way, the sector.
• Increase amongst parking bays in the center town through the adoption of the temporary parking paying and the construction of the multistory parking lots.

The absence of the concrete measures aiming at the control of the through traffic of the vehicles by the center town is the essential cause of the packing of circulation and the congestions of the roads.

Also, the absence of the network of roads peripheral, able to absorb the traffic generated the saturation of the only Southern road axis - North.

• The inadequacy of the installation and the programming of certain crossroads of the communal zone and the primary roads to the needs for the traffic.
• The multiplication of the speakers in public transport and the absence of coordination between them as well as the lack of complementarily enters the networks available.
• The modesty of the level of the services of public transport and the overload of the means in particular during the rush hours.
• The saturation of the common section: the terminus of the buses on the level of the stations of Habib Thameur and Ali Belhoaune for TRANSTU, the Republic for the subway and Barcelona and Tunis Navy for the common trunks.
